Area of a Square. Square is a polygon with four equal sides in length and has four equal angles. Each angle is 90 degrees (or right angle). In order to calculate the area of a square, multiply the length of two sides (each side is equal in length). The calculator below can be used to calculate the area of a square.
Tooth or dental trauma is injury to the mouth, teeth, soft oral tissues or jawbones. Tooth trauma can be caused by sports, car accidents, fights, falls, biting on hard foods/objects and drinking hot liquids.racked Teeth: Apart from injury to the tooth, habits such as teeth grinding, clenching and chewing on hard objects can cause cracked teeth. Symptoms of cracked teeth include erratic pain from chewing and temperature extremes. Pulp irritation and damage may result.
Cavities: Holes or structural damage in the two outer layers of a tooth called the enamel and the dentin. The enamel is the outermost white hard surface and the dentin is the yellow layer just beneath enamel. Both layers serve to protect the inner living tooth tissue called the pulp, where blood vessels and nerves reside. Cavities are caused by bacteria in the mouth. Small cavities may not cause pain, and may be unnoticed by the patient. Larger cavities can collect food, and the inner pulp of the affected tooth can become irritated by bacterial toxins, foods that are cold, hot, sour, or sweet - causing toothache.
